目的 :探讨经阴道彩色超声多普勒显像 (TVCDI)与CA12 5联合筛查高危人群卵巢良恶性肿瘤的临床应用价值。方法 :高危人群组 6 0 1例 ,对照组 5 0例 ,均作TVCDI与CA12 5联合筛查 ,以RI <0 .44,CA12 5 >35U/ml作为判断卵巢良恶性肿瘤鉴定值 ;确定恶性肿瘤高危指标 (RMI) ,以RMI≥ 3项者作为良恶性肿瘤鉴定指标。结果 :经手术病理证实的卵巢肿瘤 48例 ,其中良性肿瘤 36例 ,恶性肿瘤 12例 ,TVCDI及CA12 5的敏感性、特异性和准确性分别为 83 .3%、91.7%、89.6 %及 6 6 .7%、88.9%、83 .3 % ,两种方法联合其敏感性、特异性和准确性提高至 91.7%、94.4%和 93 .7%。 12例卵巢恶性肿瘤均具备RMI 3项或 3项以上。结论 :TVCDI与CA12 5联合筛查高危人群应列为首选方法 ,对鉴别卵巢肿瘤良恶性具有应用价值
Objective: To investigate the clinical value of transvaginal color Doppler ultrasound imaging (TVCDI) combined with CA12 5 in the screening of benign and malignant ovarian tumors in high-risk population. Methods: The high-risk group of 601 patients, the control group of 50 patients were screened TVCDI and CA12 5, with RI <0.44, CA12 5> 35U / ml as benign and malignant ovarian tumor identification value; to determine High-risk indicators of malignancy (RMI), with RMI ≥ 3 items as benign and malignant tumor identification. Results: There were 48 cases of ovarian tumors confirmed by operation and pathology, including 36 cases of benign tumors and 12 cases of malignant tumors. The sensitivity, specificity and accuracy of TVCDI and CA12 5 were 83.3%, 91.7%, 89.6% and 6 6 .7%, 88.9%, 83 .3%. The sensitivity, specificity and accuracy of the two methods were improved to 91.7%, 94.4% and 93.7% respectively. 12 cases of ovarian cancer have RMI 3 or more. Conclusion: The combination of TVCDI and CA12 5 in screening high-risk population should be the preferred method, which has the value of discriminating benign and malignant ovarian tumors
